R503 Finger Print Reader - Serial 3.3V
Secure your project with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. It even has an LED ring built around the detection pad, which can be set to red, blue or purple (as well as some fading/blinking effects) for a great user experience.
These modules are typically used in safes - there's a high powered DSP chip that does the image rendering, calculation, feature-finding, and searching. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash, and search. You can also enroll new fingers directly - up to 200 fingerprints can be stored in the onboard FLASH memory.
We like this particular sensor because its a nice rugged metal body, with panel-mounting that will make it easy to add to any product or project. It also comes with a 6-pin Qwiic/JST-SH 1mm pitch connector, which you can easily cut off and solder directly to the wires.
